hi, When i read forum, everyone says title, keywords and description are so important for SEO. But what about abstract? It is important? we can use same time "description and abstract"?it will help us for more or it is nothing? thanks so much.
The Abstract META tag is very similar to the description Meta tag, except its an abstraction or a brief summary of the description META tag. Generally the Abstract META tag is a one line sentence which gives an overview of the entire webpage. Although search engines do not as often use this tag, it is a useful complement to search engines that read the first few lines of text of your webpages. <META name="Abstract" content="Abstract phrase">
I've never learnt that before. It's probably not much weight in affecting your seo, but try it and compare. Who knows, it might be the missing link that the gurus are keeping away from us.
It won't affect SEO at all, but it improves the visibility and accessibility of your content when you are more effectively able to communicate your purpose to potential visitors.
